Subject: [PATCH 13/19] drm/amdgpu: Use RLCG to program GRBM_GFX_CNTL during full access time
Date: Tue, 30 Aug 2022 14:40:06 -0400	[thread overview]
Message-ID: <20220830184012.1825313-13-alexander.deucher@amd.com> (raw)
In-Reply-To: <20220830184012.1825313-1-alexander.deucher@amd.com>

From: Yifan Zha <Yifan.Zha@amd.com>

[Why]
KIQ register init requires GRBM_GFX_CNTL to select KIQ.

[How]
As RLCG accessing registers will save the data of GRBM_GFX_CNTL and restore it.
Use RLCG indirect accessing register method to select grbm instead of mmio directly access.
